Click event not working in bootgrid formatters

Question

In JQuery-bootgrid formatters I am not able to call the click method.
If you have any idea what could be wrong please post here.

How to use the click event in KO using bootgrid?

This is my code:

function VM() { 
  var self = this; 
  self.GetDetails = function(_e,actionType) { 
    alert("Hi"); 
  } 
} 
var s = $("#UserList").bootgrid(
  { caseSensitive: false, 
    formatters: { 
      "Actions": function (column, curr) { 
         return "<a href='#' data-bind='click:GetDetails' class='on-default edit-row'>Hello</a>"; 
      } 
    } 
  }
).bootgrid("append", data); 
vm = new VM(); 
ko.applyBindings(vm,document.getElementById("MyDiv")[0]); 
})
